  <h1 class="topictitle1">Debugging Macros</h1>
 
   
  <div> 
	 <p>The names of the debugging macros have changed as
		shown in Table 45. If you define the old macros, the Intel&reg; Threading Building Blocks (Intel&reg; TBB) 
        library sets each undefined new macro in a way that duplicates the behavior the old macro settings. 
	 </p>
 
	 <p>The old 
		<span class="keyword">TBB_DO_ASSERT</span>
		enabled assertions, full support for Intel&reg; Threading Tools, and performance
		warnings. These three distinct capabilities are now controlled by three
		separate macros as described in Enabling Debugging Features. 
	 </p>
 
	 <div class="Note"><h3 class="NoteTipHead">
					Tip</h3> 
		<p>To enable all three capabilities with a single
		  macro, define 
		  <span class="keyword">TBB_USE_DEBUG</span>
		  to be 1. If you had code under 
		  <samp class="codeph">"#if TBB_DO_ASSERT"</samp>
		  that should be conditionally included only when assertions are enabled, use 
		  <samp class="codeph">"#if TBB_USE_ASSERT"</samp>
		  instead.
